Press Release: Product Announcement
Sensirion AG, 8712 Staefa, Switzerland
First digital differential pressure sensor – long-term stable and economical
Summary
With its SDP600 series, Sensirion is bringing the world’s first digital dynamic differential pressure sensors on the market. The fully calibrated sensors feature high sensitivity and accuracy even at low pressuredifferences (less than 10Pa). The SDP600 and SDP610 provide a digital output and are extremely reliable due to their absence of offset and drift errors. Thanks to their small package size and high level of integration, these innovative sensor products can be supplied at economical prices.
Fulltext
It is a well-known fact that using a differential pressure sensor can facilitate improved control and monitoring in many application scenarios. However, this requires a sensor that operates with high precision and reliability, and which, ideally, also helps reduce costs. With the newly developed SDP600 and SDP610, Sensirion AG is launching a pair of dynamic differential pressure sensors that can fulfill these demanding requirements.
The SDP600 and SDP610 supply a digital I2Coutput signal with a measuring range of -500 to +500Pa.Even at low differential pressures (less than 10 Pa), the sensor achieves outstanding accuracy and sensitivity. This perfor-mance is based on a dynamic measuring principle in which the differential pressure is determined using intrinsic flow measurement. The SDP600 series sensors are not affected by offset and drift errors and feature an outstanding dynamic pressure range.Intelligent packaging with a corre-spondingly compact package size allows lower manufacturing costs and thus acompetitive price. In addition, the high level of integration may reduce the total electronic component count in the applications these fully calibrated sensors are used with.
The new differential pressure sensors are available in two versions. The SDP600 is intended for a direct threaded connection to a pressure manifoldvia O-ring sealing, while the SDP610 is designed for a hose connection. The outstanding performance results from the device’s sensor chip, which is based on Sensirion’s unique, patented CMOSens® technology. With this technology, Sensirion has succeeded in completely integrating a thermal sensor element and full signal conditioning circuitry on a single semiconductor chip. Thanks to large-scale fabrication of CMOSens® devices, these microchips can be produced in large volume with consistently high quality.
The SDP600 seriesis especially well suited for use with medical equipment and HVAC applications (heating, ventilation, air conditioning). For example, the sensors can be used to increase the functional scope and energy efficiency of burner con-trollers and artificial respiration devices. This in turn enhances comfort and leads to significant cost reductions.
